A length of wire, typically U-shaped, designed to mechanically fasten internal tissues together (e.g., the subcuticular closure of skin or the approximation of the ends of bowel) to facilitate healing typically in abdominal, thoracic, gynaecologic, orthopaedic, or plastic and reconstructive surgery. The device is made of a material that cannot be chemically degraded or absorbed via natural body processes (e.g., implant grade metal). This is a single-use device.
